ASTM C791 : 04

Standard Test Methods for Chemical, Mass Spectrometric, and Spectrochemical Analysis of Nuclear-Grade Boron Carbide

Standard Details

1.1 These test methods cover procedures for the chemical, mass spectrometric, and spectrochemical analysis of nuclear-grade boron carbide powder and pellets to determine compliance with specifications.

1.2 The analytical procedures appear in the following order:

Total Carbon by Combustion and Gravimetry	7-17
Total Boron by Titrimetry	18-28
Isotopic Composition by Mass Spectrometry	29-38
Chloride and Fluoride Separation by Pyrohydrolysis	39-45
Chloride by Constant-Current Coulometry	46-54
Fluoride by Ion-Selective Electrode	55-63
Water by Constant-Voltage Coulometry	64-72
Impurities by Spectrochemical Analysis	73-81
Soluble Boron by Titrimetry	82-95
Soluble Carbon by a Manometric Measurement	96-105
Metallic Impurities by a Direct Reader Spectrometric Method	106-114
